Agglomerative coefficient and pseudo- statistic for hierarchical clustering.

Number of clusters	Agglomeration last step	Coefficient current step	Score change	Pseudo-	value
2	2847.045	2516.781	330.264	1533.167	0.000
3	2516.781	2307.600	209.181	767.332	0.000

Demarcation point → 2 clusters.
Ratio of between-cluster variance to within-cluster variance largest → 2 clusters.
